[0027] The secondary crushing mechanism 10 includes a drive motor 1001 fixedly installed on one side of the drive box 6. The output end of the drive motor 1001 is connected to a crushing roller 1002. A sprocket 1003 is installed at one end of the crushing roller 1002. A crushing roller 2 1004 is provided on one side of the crushing roller 1002. A sprocket 2 1005 is installed at one end of the crushing roller 2 1004. A chain 1006 connects the sprocket 1003 and the sprocket 2 1005.

[0028] Through the above scheme, drive motor 1001 starts, driving crushing roller 1002 to rotate. Crushing roller 1002 is driven by chain 1006, driving crushing roller 1004 to rotate synchronously. Crushing roller 1002 and crushing roller 1004 perform secondary crushing on the material falling into grinding box 9, further refining the particle size.

[0029] The feeding mechanism 4 includes a pair of mounting plates 401 fixedly mounted on the support frame 3. A second drive motor 402 is mounted on one side of the mounting plate 401. A drive wheel 403 is driven to the output end of the second drive motor 402. An auxiliary wheel 404 is rotatably connected to one end of the mounting plate 401. A guide plate 405 is mounted on one end of the mounting plate 401. A conveyor belt 406 is connected between the drive wheel 403 and the auxiliary wheel 404.

[0030] Through the above scheme, the polymer material is placed in the raw material frame 13, the drive motor 402 is started, and the drive wheel 403 is driven to rotate. The drive wheel 403, through the cooperation of the conveyor belt 406 and the auxiliary wheel 404, transports the polymer material from the raw material frame 13 to the discharge port 5 of the crushing box 2. The guide plate 405 ensures that the material falls into the crushing box 2 evenly and stably.

[0031] The primary crushing mechanism 8 includes a drive motor 801 fixedly installed on the top of one side of the crushing box 2. The output end of the drive motor 801 is connected to a rotating shaft 802. A crushing rod 803 is installed on the rotating shaft 802, and a crushing block 804 is installed on the crushing rod 803.

The ground material falls into the lower wall of the crushing box 2 through the outlet at the bottom of the grinding box 9, and slides down the inclined plate 12 to the discharge pipe 7.

[0035] A raw material frame 13 is installed on one end of the upper surface of the base 1.

[0036] The working principle of this utility model patent is as follows: First, the polymer material to be crushed is placed in the raw material frame 13, ensuring that the amount of raw material is appropriate and avoiding too much or too little material from affecting the crushing effect. The drive wheel 403, through the cooperation of the conveyor belt 406 and the auxiliary wheel 404, continuously and evenly conveys the material in the raw material frame 13 to the discharge port 5 of the crushing box 2. The drive motor 801 is started, driving the rotating shaft 802 to rotate. The crushing rod 803 and crushing blocks 804 on the rotating shaft 802 rotate with the rotating shaft, performing initial crushing on the raw material falling from the discharge port 5. The material is crushed, and the drive motor 1001 is started simultaneously. This motor drives the crushing roller 1002 to rotate. The crushing roller 1002 drives the crushing roller 1004 to rotate synchronously through the chain 1006, which performs a secondary crushing process on the material after the initial crushing. The material after secondary crushing falls into the grinding box 9, ready for grinding. The grinding disc 1102 cooperates with the circular cylinder 1103 and grinding head 1104 in the grinding box 9 to perform fine grinding on the material falling into the grinding box until the required particle size is achieved.
